3. Give your dog extra water.

4. Offer your dog several ways to cool off.

Leave a fan on in a place where your dog can sit in front of it, add some ice cubes to his water or offer him a cool treat. (A Kong that’s stuffed with wet food or peanut butter, then frozen, is cooling and a great way to keep your dog entertained.) (Photo: Thinkstock)

5. Never leave your dog alone inside a car.

Even with the windows cracked, the inside of a car can heat up to 120 degrees in a matter of minutes on a warm day. And leaving the air conditioning on is no guarantee that your dog will be safe. Watch this PSA about pets in hot cars. (Photo: Thinkstock)

6. Take your walks in the morning or evening.

The intense heat of midday can overwhelm your dog during a walk. Exercise your dog during the cooler hours and, if your dog is in the sun for an extended period of time, apply doggie sunscreen. Learn more about sunscreen for pets. (Photo: Thinkstock)

7. Don’t leave your dog alone outside for more than a few minutes.

8. Avoid hot sidewalks.

9. Brush your dog regularly.

A clean, untangled coat can help ward off summer skin problems and help your dog stay cool. If you want to give your dog a haircut, and your vet thinks it will help him cope with the heat, keep his fur at least one inch long to protect him from the sun. (Shaving down to the skin is not recommended.) (Photo: Thinkstock)

10. Be alert for coolant leaking from your vehicle.

Dogs are attracted to the sweet taste of coolant, and just a small amount can make your dog sick — or even cause death. If you believe your dog may have ingested coolant, take him to the vet right away. (Photo: Thinkstock)
